Where might one find the Efs folder on this phone
Sent from my HTC Vision using XDA
not sure if youll find a efs folder for i dont think its part of the rom rather writen into the radio. just a guess. maybe try the search function in root explorer or similar file manager. or open up a supewipe that contains a efs wipe and see if there is a directory of sorts there.

EFS is a partition, not a folder, and as such you can't find it w/ a regular file browser.

If you use the EXT4 Superwipe [link] it will format your EFS partition (and all others except sdcard, BACKUP FIRST!!!!), but will backup your EFS partitions to your sdcard as part13 & 14.
will i be able to save it to my computer

Why do you want to backup your partition with imei data?
There is no way to write to where the imei data is, even with S-OFF, all partitions below 7 inclusive (and a few others I think) are write protected

isn't that the point of root access to be able to write or read any filesystem on device? Anyways the reason i want to back the efs(imei) is if i somehow screw it up by flasing something. Example coming from samsung. When i first started to play with root and roms i ran out of things to flash so i decided to carrier unlock my device. I was successful except my imei was gone meaning it read all 00000000000000 . Up until this happened i never even heard of efs let alone seen any threads that discussed it. Long story short a Dev from another community was able to help me restore it even without a backup SGS4g devs had no fix to restore . Also this device is still stuck on GB no ics love yet, we do however have a working version of CM7. our devs have implemented automatic efs backup everytime new rom is flashed now and when we install cm7 we have to flash a EFS backup.zip first, complete wipe, then EFS restore.zip.then we can flash CM7 rom other wise it wiil erase IMEI leaving all 0000000000000 . So thats why i want to back it up since there is no way to simply rewrite your IMEI . Sorry for the long rant.

When you flash a non sense rom you will lose those folders because sense uses them for sim card information etc on cm7 that information is built in to the framework. So don't worry the files are missing your phone will still work as normal

Hi,
I have almost the same problem like y.trumper:
I cannot find the efs-folder on my rooted Wildfire S, BUT I'm still using STOCK rom with HTC Sense...
(I've just rooted and tried to find the efs folder for a backup before installing custom rom...)
Could anbody explain how to find the efs-folder in order to copy it?
You can't find this folder/partition because it doesn't even exist. Therefore, there's no need to backup anything else than your data (apps, contacts etc). Just flash your desired Custom ROM!

Thanks! Can you explain to me how it works then? Is it impossible to loose the IMEI number when something goes wrong during flashing?
Just go here and here. And no, normally you shouldn't lose your IMEI (depends on what you flash and how!). But if you just follow the instructions given in our fora, nothing can happen as the Wildfire S is nearly unbrickable.
Hello.
Sorry for language mistakes, I don't learn english too much
About 2 months ago I missed imei by flashing custom rom. I thought that warranty is missed too, but service repaired my phone (at least I thought like that).
Now I want to backup efs folder, but it isn't existing . I searched with root explorer and it didn't show any efs folder.
It is surprise, that after typing *#06# phone show correct imei.
How can I create efs folder or backup imei without efs?

U cant access efs through ur phone(i mean using root explorer u cant backup efs folder) U will need to use ADB to backup although it is not needed to backup efs because custom rom only flashes the modifed firmware it does not flash baseband,imei etc. Only thing is u need to be careful with doing this kind of things.
Press thanks if helped.
That's it.
You can use EFS Backup. I strongly recommend it.

(GUIDE)EFS/Emergency calls only/not registered with network- WHY, WHEN & HOW TO SOLVE
HI Mates, there are already a lot of comments posted about efs. But I think a detail need to talk about. Here we are:
# suddenly you find that your phone is not getting the network. When you try to make a call it says: not registered with network. Problem remains even after restock.
WHY & WHEN
usually it happens while you flash(sometimes dirty) roms often and/or
Switching from AOSP to AOKP to SAMMY vice versa. .
HOW TO SOLVE
as you are flashing roms, naturally you are rooted and you have a root explorer. Roms from 4.1 and later ones automatically creats a efs back up while you flashing a new one. When you found the disturbances, with a root explorer search for the folder "efs_Backup".
The location varies from rom to rom. You may find it under sdcard, may find under /data/media or somewhere else. After you find the folder
Open it
You will find several zip files created in different dates. Those dates are your rom flashed dates.
Choose the right dated one remembering when your phone was fine.
Extract the zip.
Go to /efs
Delete entire contents of the folder.
Go to the efs zip extracted folder.
Selct all and move them to the /efs folder.
Your phone is back as normal!

EFS Restore
Hi,
You are gr8..After 2 days of efforts, finally my phone started working..
Hi, I stupidly went back to stock and lost my imei number without making a efs backup, when I used aroma it asked if I wanted to make an efs backup and I said yes.
Would that backup help me in returning fully to stock rom? If so, where would that backup be stored in my phone?
Hope someone can help
Thanks a lot

The backup you made will be no good cause it will contain the efs of the new rom you installed.. you can check though. The efs backup will be on your sd card..
Sdcard/EFS
In efs theres folders inc imei wifi bluetooth etc
Sent from my GT-N7105 using xda premium
Do I have to be rooted to see that folder? As its not in my sd card, the only way I can see that folder is in root explorer but im not rooted at the moment.
Can I ask one more question? If I were to put stock rom back on my phone and use newer modem, my imei and network will come back, would I be able to get ota updates? Because when ive tried to search for an update, it would just hang on searching.

Yes. Copy them to your pc under efs backup aswell for safe keeping. There are guides on here of how to restore your efs with 4.1.2 roms but you will need root.
As you have efs backup I found this for you. Make sure you read and understand before doing anything..

That zip file in the link is a app. Download install.. if you backed up the efs on the stock rom before flashing the new rom it will work..
The only other thing to do is flash this modem via cwm recovery.
It says it fixes the problem

You've backed up the new modified efs folder which is only compatible with the new firmwares. You can restore from that backup, in fact you need to, but there is no going back to old firmware now. You can achieve stock if you download and flash a stock rom of version DME6 or newer, but you can never use anything older again.

How would I go about restoring that backup from efs pro? As when I am trying to select it in the restore section of efs pro it can not be seen in drop down box?
It is in tar format, there is a pit file with it but I guess as I wiped everything out of my actual efs folder through root explorer it might not work.
Also I have a pop up on my screen with loads of different information like an error pop up? I cant screen shot it other wise I would show u

Try unpacking the tar.gz, copy the the efs map to the root with the original name ofcourse(With Root Explorer AND WITH READ WRITE PERMISSION!), then reboot. I've had the same situation as you do, this was the only fix for me.
Thanks for reply, I got efs pro to work in the end but my phone is still ****ed it has no imei or serial number? Ive been looking for a solution all day.
Its also still in factory mode it says h/w not active and rf cal date unknown.
I also tried what u said and it says theres not enough space in the folder when I copy it? Its an efs.img file? And its 20mb in size. I swear if I get this sorted im never rooting my phone again.

You might need to repartition the phone using a PIT file if you completely removed the folder (and not just the contents).
Reinstall your stock rom using a PIT file in ODIN and after the restoration is done try to restore your EFS again. It should work now!

I'm having almost the exact same problem as OP. 2 questions. When you say "copy the efs map" what do you mean by that? All the contents of my unpacked efs .tar.gz backup file? Also, what do you mean by "with the original name"? Thanks!
After restoring the rom with a pit file, did you try restoring the EFS using EFSPro? You should be able to do it just using the restore option in that app, although you should be rooted to be able to restore it.
And what do you mean by "put it back using root explorer?"

Yeah after flashin a stock rom with pit file I used efs pro to restore the backup but that didnt work, I can only assume that the back up is corrupt as well? Basically I deleted everything in my efs folder so that I wiped my imei and serial number, my imei is 4000000 and serial number is 0000000, so what I done was change my serial number in root explorer from 0000000 to my actual serial number which is behind my battery, ive rebooted and flashed another stock rom since then and it hasnt changed, but my imei is still ending with 400000.
So if my backup is corrupt? I have no idea what my options are? Ive had nothing but a headache the last 2 days trying to fix it.

Did you root after restoring the backup? And did you also enable USB debugging? As I recall, EFSPro requires those to work optimally. And one last thing: did you use the latest version?
I rooted before I restored on efs pro, also what do mean by using latest version? If u mean stock rom? I used DMC3-BTU, thats the only one I had on my computer at the time, I flashed that with a pit file dated 2/11/2012?? Then I rooted and tried to restore the phone but it didnt work? I then thought as the firmware was old I would put a DF1 modem on it but that still didnt work either? Am I doing something wrong? Im going out my mind trying to sort this out!
Thanks alot

Oh also I restored on old version of efs pro I think it was version 1.93 or summink, as that is the only version that will locate the backup file in the drop down menu?? I just tried the version in the link u gave me but still same? It recognises my phone but when I use the restore drop down bit it is blank? I try to refresh but still blank?? I think it might have something to do with the restore file not being in tar.gz format? I somehow unzipped it and now its just a tar file? I dont know how to rezip the file? Any ideas please would be great.

What are the contents of the tar.gz? I mean: if you open it with winrar / 7z, etc, what do you see?
For instance, when I open my EFS tar.gz backup, I see a single file called efs.img:
If you have that as well, you could try restoring your EFS using DD by putting the EFS.img in the root of your SD card and typing the following commands on ADB Shell:
Code:
adb shell su -c "dd if=/sdcard/efs.img of=/dev/block/mmcblk0p3 bs=4096"
Well ive repackaged the tar file to tar.gz and now efs pro has located the file but I click restore and a pop up comes onto the screen saying *you must select one partition to restore???? I dont know what that means??

So I rebooted ion to revocery and did a "fix Permissions". it took forever but after that my phone worked lika new again.
